   You can use \text{-} from latex->amsmath package instead of "-". The problem seems to be with the conventional latex rendering of "-" sign.
   Try this code:-

   import numpy as np
   import matplotlib.pyplot as plt
   import matplotlib as mpl
   plt.switch_backend('Qt5Agg')
   
   mpl.rcParams.update({'text.usetex': True})
   params = {'text.latex.preamble' : [r'\usepackage{amsmath}']}
   plt.rcParams.update(params)
   fig = plt.figure()
   p=plt.imshow(np.random.random([20,20])-.5)
   cb=plt.colorbar(p, orientation="horizontal")
   
   
   labels = []
   # Replace '-' with 'amsmath>> \text{-}'
   for num in cb.ax.get_xticklabels():
       num = num._text
       labels.append(r'$\text{-}' + num[2:]  if num[1] == '-' else r'' + num) 
       
   #print(labels)
   cb.ax.set_xticklabels(labels)
   plt.savefig('new.png')
   
   plt.show()
